Abstract
Description
本発明は、空気調和機や給湯機などのヒートポンプ応用製品において、冷媒を圧縮するスクロール圧縮機に関するものである。 The present invention relates to a scroll compressor that compresses a refrigerant in a heat pump application product such as an air conditioner or a water heater.
従来から摺動抵抗の低減の目的で、非旋回スクロール板の圧縮室の最外周の角部に面取りをし、旋回スクロール板の摺動抵抗を低減しようとした例がある。 Conventionally, for the purpose of reducing sliding resistance, there is an example in which chamfering is performed on the outermost corner of the compression chamber of the non-orbiting scroll plate to reduce the sliding resistance of the orbiting scroll plate.
しかしながら現在の密閉型スクロール圧縮機の高効率・高信頼性のため、旋回スクロールと非旋回スクロールの摺動部の潤滑性が重要となっている。 However, the lubricity of the sliding parts of the orbiting scroll and the non-orbiting scroll is important for the high efficiency and high reliability of the current hermetic scroll compressor.
前記課題を解決するため、非旋回スクロールに配設した給油溝の外側角部のエッジをクラウニング処理を施したものとすることで、旋回スクロールの外周部との接触時の潤滑性を確保し、圧縮機の信頼性を向上させることが可能となる。さらに、旋回スクロール支持部材との衝突を回避するため、旋回スクロール板の摺動面の角部を面取り加工して鈍角形状とする。 In order to solve the above-mentioned problem, by ensuring that the edge of the outer corner of the oil supply groove arranged in the non-orbiting scroll is subjected to crowning treatment, the lubricity at the time of contact with the outer periphery of the orbiting scroll is secured, It becomes possible to improve the reliability of the compressor. Furthermore, in order to avoid a collision with the orbiting scroll support member, the corner portion of the sliding surface of the orbiting scroll plate is chamfered into an obtuse angle shape.
旋回スクロール板の外周角部が、非旋回スクロール板に配設した給油溝の外周角部と接触および非接触を繰り返すような揺動運動する際において摺動部の潤滑性を確保することが可能となり、より高い信頼性を確保することが可能となる。 It is possible to ensure the lubricity of the sliding part when the outer peripheral corner of the orbiting scroll plate performs a swinging motion that repeats contact and non-contact with the outer peripheral corner of the oil supply groove disposed on the non-orbiting scroll plate. Thus, higher reliability can be ensured.
請求項１記載の発明は非旋回スクロール板を支持する部材の前記旋回スクロール板との摺動面に前記回転軸と同心のリング状の給油溝を配設されたスクロール圧縮機で前記給油溝の外周側角部と前記旋回スクロールが揺動運動し接触する場合において、前記外周側角部に微小なクラウニング処理を施したものであり、この構成であれば旋回スクロール板の外周角部との摺動部潤滑が接触・離反を繰り返す揺動運動時においても接触部の潤滑状態を円滑にすることができ、前記旋回スクロールの摺動部磨耗や発熱を抑えることが可能となり、より高い信頼性を確保することが可能となる。 The invention according to claim 1 is a scroll compressor in which a ring-shaped oil supply groove concentric with the rotary shaft is disposed on a sliding surface of a member supporting a non-orbiting scroll plate with the orbiting scroll plate. When the outer peripheral corner and the orbiting scroll come into contact with each other in a swinging motion, the outer peripheral corner is subjected to a fine crowning process. With this configuration, the sliding with the outer peripheral corner of the orbiting scroll plate is performed. Even during a swinging motion where the moving part lubrication repeats contact and separation, the contact part can be smoothly lubricated, and the sliding part wear and heat generation of the orbiting scroll can be suppressed, resulting in higher reliability. It can be secured.
請求項２記載の発明は前記旋回スクロール板外周角部の硬度が前記非旋回スクロール板の摺動面に対し高く、揺動運動する際に前記非旋回スクロールに配設した前記給油溝の外
周角部との接触する場合において前記旋回スクロールの摺動部磨耗や発熱を抑えることが可能となり、より高い信頼性を確保することが可能となる。
According to a second aspect of the present invention, the hardness of the outer peripheral corner portion of the orbiting scroll plate is higher than the sliding surface of the non-orbiting scroll plate, and the outer peripheral angle of the oil supply groove disposed in the non-orbiting scroll when swinging. In the case of contact with the part, it is possible to suppress the sliding part wear and heat generation of the orbiting scroll, and it is possible to ensure higher reliability.
請求項３記載の発明は前記旋回スクロール板の外周角部をテーパ状若しくは丸くされて鈍角形状に加工することにより、前記旋回スクロールが揺動運動する際に前記非旋回スクロールに配設した前記給油溝の外周角部との接触する場合において記旋回スクロールの摺動部磨耗や発熱を抑えることが可能となり、より高い信頼性を確保することが可能となる。 According to a third aspect of the present invention, the outer corner portion of the orbiting scroll plate is tapered or rounded so as to have an obtuse angle shape, thereby providing the oil supply disposed in the non-orbiting scroll when the orbiting scroll swings. In the case of contact with the outer peripheral corner of the groove, it becomes possible to suppress the sliding portion wear and heat generation of the orbiting scroll, and it is possible to ensure higher reliability.
請求項４記載の発明は前記請求項１から３にいずれかの発明において前記非旋回スクロール板に配設した前記給油溝の外周角部に設けるクラウニング処理をバネにより支持される研磨石により加工することで数μｍ単位での処理が可能となり、より潤滑性を確保することが可能なクラウニング処理を実現することが可能となる。 According to a fourth aspect of the present invention, in any one of the first to third aspects, the crowning process provided at the outer peripheral corner of the oil supply groove disposed on the non-orbiting scroll plate is processed by a grinding stone supported by a spring. Thus, processing in units of several μm is possible, and it is possible to realize a crowning process that can ensure more lubricity.
請求項５記載の発明は請求項４記載の発明において前記非旋回スクロールに配設した前記クラウニング処理時に研磨石の中心位置を前記給油溝の内部に設定することにより前記研磨石を指示するバネ力との間でアンバランスが生じ、研磨石が傾くため数μｍ単位での処理が可能となり、より潤滑性を確保することが可能なクラウニング処理を実現することが可能となる。 According to a fifth aspect of the present invention, in the fourth aspect of the invention, the spring force that indicates the grinding stone by setting the center position of the grinding stone inside the oil supply groove during the crowning process disposed on the non-orbiting scroll. Since an unbalance occurs between them and the polishing stone is tilted, it is possible to process in units of several μm, and it is possible to realize a crowning process that can ensure more lubricity.
以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.
（実施の形態１）
図１および図２にて、第１の実施例を説明する。図１は、圧縮機構部の説明図であり、旋回スクロール板外周角部１１の可動範囲と非旋回スクロール板溝部２１の位置関係を示したものである。図２は、電動機の回転軸（図示せず）の中心を通る平面且つ旋回スクロール板１０が最も偏心した位置での関係を示す断面図である。
(Embodiment 1)
A first embodiment will be described with reference to FIGS. FIG. 1 is an explanatory diagram of the compression mechanism, and shows the positional relationship between the movable range of the orbiting scroll plate outer peripheral corner 11 and the non-orbiting scroll plate groove 21. FIG. 2 is a cross-sectional view showing a relationship between a plane passing through the center of a rotating shaft (not shown) of the electric motor and a position where the orbiting scroll plate 10 is most eccentric.
密閉容器（図示せず）内に収納された電動機部（図示せず）と、その電動機部によって駆動される台板とその台板上に一体的に形成された渦巻状のラップを有する旋回スクロール板１０と、その旋回スクロール板１０と組み合わされる台板とその台板上に一体的に形成された渦巻状のラップを有する非旋回スクロール板２０とにより構成される圧縮機構部とを具えたスクロール圧縮機において、前記非旋回スクロール板２０と前記旋回スクロール板１０との摺動面に給油溝２１を備え、この溝２１への潤滑油が旋回スクロール１０を非旋回スクロール２０に押し付けるために設けられる背圧室（図示せず）により供給されるため、旋回スクロール１０の旋回時に必ず給油溝２１が背圧室に連通する必要がある構造において、この溝２１の外側角部２１ａと旋回スクロール板外周角部１１が接触・離反を部分的に揺動するため、旋回スクロール板外周角部１１と溝の外周側角部２１ａとの衝突により潤滑が途切れる等の影響をなくすように外側角部２１ａに図３にあるような数μｍのクラウニング処理部２５を施すことにより、旋回スクロール板外周角部１１の傾斜部が接触・離反の揺動運動する際の衝突による影響をなくし、潤滑性を向上させることが可能となるため、旋回スクロール板外周角部１１や非旋回スクロール２０の給油溝外周角部２１ａ摺動部分の潤滑不足による発熱・磨耗を抑えることができ、信頼性の向上を図ることができる。
（実施の形態２）
図４にて、第２の実施例を説明する。図４は非旋回スクロール板２０に配設した給油溝２１に高速回転する研磨ツール３０を配置した場合の拡大図である。非旋回スクロールの外側角部２１ａを数μｍのクラウニング処理を施すために、高速回転する研磨ツール３０を用いるが、回転する根元にはバネが配置されており、ある一定負荷以上には面圧が高ま
らないように設計されている。そのため、給油溝２１の外周角部２１ａ部分において研磨ツール３０の一部が給油溝２１上にはみ出るよう図のように配置し、非旋回スクロール中心を基点として回転研磨することにより高精度でのクラウニング処理を行うことが可能となる。
（実施の形態３）
図５にて第３の実施例を説明する。図５は高速回転する研磨ツール３０を用いて給油溝２１にクラウニング処理を施す詳細拡大図である。研磨ツールは高速回転するため円筒で形成されており、その径は給油溝２１の幅の２倍以下となるように設定し、その中心軸を意図的に給油溝２１内部に配設することによりバネの押し付け力により破線のように研磨ツール３０は給油溝２１内部に入り込むことになり、給油溝２１の外周角部２１ａに対しより滑らかなクラウニング処理を施すことができる。更にクラウニングの径方向の長さについても研磨ツール３０の（半径−ツール中心軸の給油溝への配置量）にて規定できるため深さ方向だけでなく、径方向についても高精度にクラウニング処理を施すことができる。
An orbiting scroll having an electric motor part (not shown) housed in an airtight container (not shown), a base plate driven by the electric motor part, and a spiral wrap integrally formed on the base plate A scroll having a plate 10, a compression plate portion composed of a base plate combined with the orbiting scroll plate 10 and a non-orbiting scroll plate 20 having a spiral wrap integrally formed on the base plate. In the compressor, an oil supply groove 21 is provided on a sliding surface between the non-orbiting scroll plate 20 and the orbiting scroll plate 10, and lubricating oil for the groove 21 is provided to press the orbiting scroll 10 against the non-orbiting scroll 20. Since it is supplied by a back pressure chamber (not shown), the oil supply groove 21 must always communicate with the back pressure chamber when the orbiting scroll 10 is turned. Since the part 21a and the orbiting scroll plate outer peripheral corner part 11 swing partially in contact / separation, the influence of the interruption of the lubrication due to the collision between the orbiting scroll plate outer peripheral corner part 11 and the outer peripheral corner part 21a of the groove is eliminated. As shown in FIG. 3, the outer corner portion 21a is provided with a crowning processing portion 25 having a thickness of several μm, so that the influence of the collision when the inclined portion of the outer peripheral corner portion 11 of the orbiting scroll plate swings in contact / separation is exerted. Since it is possible to improve the lubricity, heat generation and wear due to insufficient lubrication of the sliding scroll plate outer corner 11 and the sliding groove outer corner 21a of the non-orbiting scroll 20 can be suppressed. It is possible to improve the performance.
(Embodiment 2)
A second embodiment will be described with reference to FIG. FIG. 4 is an enlarged view when a polishing tool 30 that rotates at high speed is disposed in the oil supply groove 21 disposed in the non-orbiting scroll plate 20. A polishing tool 30 that rotates at a high speed is used to perform a crowning process of several μm on the outer corner portion 21a of the non-orbiting scroll. However, a spring is disposed at the root of the rotation, and a surface pressure exceeds a certain load. Designed not to rise. For this reason, a part of the polishing tool 30 is arranged as shown in the figure at the outer peripheral corner 21a of the oil supply groove 21 so as to protrude over the oil supply groove 21 and is ground with high accuracy by rotating and polishing with the center of the non-orbiting scroll as a base point. Processing can be performed.
(Embodiment 3)
A third embodiment will be described with reference to FIG. FIG. 5 is a detailed enlarged view of applying a crowning process to the oil supply groove 21 using the polishing tool 30 that rotates at high speed. The polishing tool is formed in a cylindrical shape because it rotates at a high speed, and its diameter is set to be not more than twice the width of the oil supply groove 21, and its central axis is intentionally disposed inside the oil supply groove 21. The polishing tool 30 enters the oil supply groove 21 as indicated by the broken line by the pressing force of the spring, and the outer peripheral corner portion 21a of the oil supply groove 21 can be subjected to a smoother crowning process. Furthermore, since the length of the crowning in the radial direction can be defined by (radius-amount of arrangement of the tool central axis in the oil supply groove) of the polishing tool 30, not only the depth direction but also the radial direction can be accurately crowned Can be applied.
以上のように、本発明にかかる密閉型圧縮機において、旋回スクロール外周部と非旋回スクロール外周部の潤滑性を向上させることが可能となり、摺動部の信頼性を向上させるスクロール圧縮機が実現可能となる。 As described above, in the hermetic compressor according to the present invention, it is possible to improve the lubricity of the outer peripheral portion of the orbiting scroll and the outer peripheral portion of the non-orbiting scroll, and a scroll compressor that improves the reliability of the sliding portion is realized. It becomes possible.
